The present inventionincludes a support base set on a floor, a seat cushion disposed at thefront end of the support base, a leg hooking rod disposed on the supportbase and under the seat cushion, a turnable backrest pivotally coupledto the support base and behind the seat cushion, a transversal rod ispivotally coupled under the backrest and disposed on the support stand,a vertical link bar fixed on both ends of the transversal rod, a rollerinstalled at the link bar, a pushing rod disposed on both ends of thetransversal rod for adjusting different widths and angles, a verticaltrack disposed on a backside of the backrest and at a -positioncorresponding to the roller, such that the roller can be moved back andforth along the track, and a weight carrying rod disposed at the top ofthe backrest for flexibly carrying a weight, and by flexibly adding orremoving a weight on the weight carrying rod, an exerciser can sit onthe seat cushion, lean his/her back against the backrest, and push thepushing rod with both hands to drive the transversal rod to turn and theroller at the end of the link bar to roll along the track, so as to pushthe backrest with the weights to elevate or lie down, and suchback-and-forth exercises can achieve the effect of exercising theexerciser's chest, abdomen, and arms, and the weights can be adjustedflexibly to fit different people and the use for a long-time training.

2. Description of the Related Art

Since people pay more attentions to their health nowadays, variousdifferent fitness equipments are introduced constantly, but the sit-upexercise is still performed without using an equipment, and factors suchas age, physical strength, and obesity may cause injuries to anexerciser's back or waist. Even though there are fitness equipments toassist the sit-up exercise, yet the sit-up exercise is monotonous andunable to provide changes or adjustments for different trainings orphysical strengths. After doing the same exercise for a long time,exercisers may find the sit-up exercise boring and no longer feel likedong the same exercise further, and thus improvements are needed.

SUMMARY OF THE INVENTION

In view of the foregoing shortcomings, the inventor of the presentinvention based on years of experience in the related field to conductextensive researches and experiments, and finally invented a waist andabdomen exercising fitness equipment.

Therefore, it is a primary objective of the present invention to providea waist and abdomen exercising fitness equipment that includes a supportbase set on a floor, a seat cushion disposed at the front end of thesupport base, a leg hooking rod disposed on the support base and underthe seat cushion, a turnable backrest pivotally coupled to the supportbase and behind the seat cushion, a transversal rod is pivotally coupledunder the backrest and disposed on the support stand, a vertical linkbar fixed on both ends of the transversal rod, a roller installed at thelink bar, a pushing rod disposed on both ends of the transversal rod foradjusting different widths and angles, a vertical track disposed on abackside of the backrest and at a position corresponding to the roller,such that the roller can be moved back and forth along the track, and aweight carrying rod disposed at the top of the backrest for flexiblycarrying a weight, and by flexibly adding or removing a weight on theweight carrying rod, an exerciser can sit on the seat cushion, leanhis/her back against the backrest, and push the pushing rod with bothhands to drive the transversal rod to turn and the roller at the end ofthe link bar to roll along the track, so as to push the backrest withthe weights to elevate or lie down, and such back-and-forth exercisescan achieve the effect of exercising the exerciser's chest, abdomen, andarms, and the weights can be adjusted flexibly to fit different peopleand the use for a long-time training.

FIG. 1 is a perspective view of a preferred embodiment of the invention;

FIG. 2 is a side view of a preferred embodiment of the invention;

FIG. 3 is a side view of another preferred embodiment of the invention;and

FIG. 4 is a schematic view of a backrest and a weight carrying rodaccording to a preferred embodiment of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

To make it easier for our examiner to understand the objective, shape,assembly, structure, characteristics and performance of the presentinvention, the following embodiments accompanied with the relateddrawings are described in details.

Referring to the figures, the present invention comprises a support base1, a seat cushion 2, a backrest 3, and a pushing rod 4, wherein thesupport base 1 is a frame set on a floor, and the support base 1 couldbe an extendable and foldable structure; the seat cushion 2 is fixed atthe front end of the support base 1 for providing a seat for anexerciser; a leg hooking rod 20 is disposed on the support base 1 andunder the seat cushion 2 for hooking the exerciser's leg; the backrest 3is turnable and pivotally coupled on the seat cushion 2 at the back ofthe support base 1; a transversal rod 10 is pivotally coupled to thesupport base I and under the backrest 3; a vertical link bar 11 is fixedto both ends of the transversal rod 10 and includes a roller 12installed at the end of the link bar 11; a pushing rod 4 is disposed atboth ends of the transversal rod 10 and capable of adjusting differentwidths and angles; a vertical track 30 is disposed at the backside ofthe backrest 3 and at a position corresponding to the roller 12, suchthat the roller 12 can be moved back and forth precisely along the track30; a weight carrying rod 31 is fixed at the top of the backrest 3, sothat a weight 32 such as a water bag and a sand bag can be added to theweight carrying rod 31 flexibly; and a support frame rod 13 is installedon the support base under the backrest 2 to restrict the link bar 11 andfurther to stop the backrest 3 from being inclined backward.

In practical applications, users can place the support base 1 on afloor, and adjust the weights 32 such as water bags and sand bags on theweight carrying rod 31 according to the exerciser's age and physicalstrength, so that different forces will be applied when the backrest 2is turned. Further, the pushing rod 4 disposed on both ends of thetransversal rod 10 can be adjusted into different angles, so as tochange the angle of elevation of the backrest 3, so that when theexerciser sits on the seat cushion 2, the exerciser can lean his/herback against the backrest 2, and push the pushing rod 4 with both handsto drive the transversal rod 10 to turn, and thus the roller 12 at theedge of the link bar 11 can be moved along the track 30 on the backrest3 to push the backrest 3 with the weights to elevate or lie down. Thebackrest 3 is restricted and stopped by the support stand rod 13. Theback-and-forth exercise can provide exercises for the exerciser's chest,abdomen, arms, and other parts of the body. In the meantime, the weights32 as well as the angle of the pushing rod 4 can be changed quickly andeasily, so that the weight and rotating extent of the backrest 3 can bechanged to fit different exercisers and the use for a long-timetraining.

The structure of the invention herein enhances the performance andovercomes the shortcoming of the prior art, and further complies withthe patent application requirements.

While the invention has been described by way of example and in terms ofa preferred embodiment, it is to be understood that the invention is notlimited thereto. To the contrary, it is intended to cover variousmodifications and similar arrangements and procedures, and the scope ofthe appended claims therefore should be accorded the broadestinterpretation so as to encompass all such modifications and similararrangements and procedures.
